Description
Seyoung Park and five co-authors measure size differences between male and female Yellow-browed Buntings, a small songbird. Their study came out in 2025. Knowing a bird's sex in the field helps explain why males and females migrate on different schedules.
The team caught first-year birds at a stopover island in South Korea and confirmed each bird's sex with a genetic test. Wing length differed most between the sexes, with tail length next. A simple rule based on wing length alone sorted the birds correctly in almost all test cases. Field workers can now sex this species quickly, without sending samples to a laboratory.
